AT-2745FX and AT-2746FX Series
The adapters in the AT-2745FX Series are:
ˆ AT-2745FX/SC
ˆ AT-2745FX/ST
ˆ AT-2745FX/STSC
The adapters in the AT-2746FX Series are:
ˆ AT-2746FX/SC/SC
ˆ AT-2746FX/ST/ST
ˆ AT-2746FX/ST/SC
The AT-2745FX and AT-2746FX Series are dual port adapters. But unlike
the other dual port adapters discussed in this guide, which feature a
twisted pair port and a fiber optic port, these adapter cards have two fiber
optic ports. One port is 10Base-FL and the other 100Base-FX. These
adapters allow you to use the same network adapter card for either 10
Mbps or 100 Mbps over fiber optic cable. The cards are appropriate in
network environments whether there is a mix of 10Base-FL and 100Base-
FX Ethernet hubs and switches. They can also be useful in 10Base-FL
environments where there are future plans to upgrade the switches and
hubs to 100Base-FX.
Note
You can use only one port on this adapter at a time. Do not attach
both ports to the network at the same time.
Differences between the two series are:
ˆ The AT-2745FX Series is PCI 2.1-compliant.
ˆ The AT-2746FX Series is PCI 2.2-compliant.
ˆ The AT-2745FX Series was offered in two versions — a standard
version and a low profile version for systems that accept only low
profile adapters.
ˆ The AT-2746FX Series can be installed in either a standard or low
profile system. The adapter comes with two brackets, one for a
standard system and another for a low profile system.
ˆ The AT-2745FX Series supported the Wake on LAN feature only on
the 100Base-FX port.
ˆ The AT-2746FX Series supports the Wake on LAN feature on both
ports.
